Abstract

The chromatographic properties of silica-immobilized 2-pyridinecarboxyaldehyde phenylhydrazone as stationary phase for separation of aqueous metal-ion mixtures containing various combinations of Mn(II), Fe(II), Cd(II), Zn(II), Co(II), Pb(II), and Cu(II) are described. Separations were achieved in many cases by using mobile phases containing chloride or perchlorate anions, at moderate flow-rates. Quantitative chromatographic analysis was possible for a variety of sample types over a wide range of metal-ion concentrations.
